Om mani padme hum

"Om mani padme hum" (Sanskrit ॐ मणि पद्मे हूँ, oṃ maṇi padme hūṃ; see other transliterations below) is probably the most famous mantra in Buddhism and Hinduism, the six syllabled mantra of the bodhisattva of compassion, Avalokiteshvara (Sanskrit. Guanyin in Chinese, Kannon in Japanese, Chenrezig in Tibetan). The mantra is particularly associated with the four-armed Shadakshari form of Avalokiteshvara. The Dalai Lama is said to be an incarnation of Avalokiteshvara, so the mantra is especially revered by his devotees.
